2022-11-05Cleanup: use bool instead of short for job stop & do_update argumentsCampbell Barton
Since these values are only ever 0/1, use bool type.

2022-06-29VSE: Improved Retiming systemRichard Antalik
Patch implements better way to control playback speed than it is possible to do with speed effect. Speed factor property can be set in Time panel. There are 2 layers of control: Option to retime movie to match scene FPS rate. Custom speed factor to control playback rate. Since playback rate is strip property, it is now possible to manipulate strip as normal one even if it is retimed. To facilitate manipulation, some functions need to consider speed factor and apply necessary corrections to strip offset or strip start. These corrections may need to be float numbers, so start and offsets must be float as well. Sound strips now use speed factor instead of pitch. This means, that strips will change length to match usable length. In addition, it is possible to group movie and sound strip and change speed of meta strip.

When handles are moved, job is created only for strips that need to update first thumbnail. ref T91618
2022-04-04VSE: Add channel headersRichard Antalik
This patch adds channel region to VSE timeline area for drawing channel headers. It is synchronizedwith timeline region. 3 basic features are implemented - channel visibility, locking and name. Channel data is stored in `SeqTimelineChannel` which can be top-level owned by `Editing`, or it is owned by meta strip to support nesting. Strip properties are completely independent and channel properties are applied on top of particular strip property, thus overriding it. Implementation is separate from channel regions in other editors. This is mainly because style and topology is quite different in VSE. But also code seems to be much more readable this way. Currently channels use functions similar to VSE timeline to draw background to provide illusion of transparency, but only for background and sfra/efra regions. Great portion of this patch is change from using strip visibility and lock status to include channel state - this is facilitated by functions `SEQ_transform_is_locked` and `SEQ_render_is_muted` Originally this included changes in D14263, but patch was split for easier review.

2022-02-11File headers: SPDX License migrationCampbell Barton
Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069

2021-09-21VSE strip thumbnailsAditya Y Jeppu
Draw thumbnails as strip overlay. This works for movie and image strips. To draw thumbnails, this overlay has to be enabled and strips must be tall enough. The thumbnails are loaded from source file using separate thread and stored in cache. Drawing code uses only images stored in cache, and if any is missing, background rendering job is started. If job can not render thumbnail, to prevent endless loop of creating job for missing image it sets `SEQ_FLAG_SKIP_THUMBNAILS` bit of `Sequence` flag. To prevent visual glitches during timeline panning and zooming, `View2D` flag `V2D_IS_NAVIGATING` is implemented. If bit is set, drawing code will look for set of evenly distributed thumbnails that should be guaranteed to exist and also set of previously displayed thumbnails. Due to volatile nature of cache these thumbnails can be missing anyway, in which case no new thumbnails will be drawn for particular strip. Cache capacity is limited to 5000 thumbnails and performs cleanup of non visible images when limit is reached. ref T89143 Reviewed By: ISS Differential Revision: https://developer.blender.org/D12266
2021-03-16VSE: Simplify proxy settingsRichard Antalik
- Remove Full Render size from VSE preview size. Use just 100% instead. - Add Use Proxies checkbox to control whether proxies are used globally - Move preview size to top so it is most prominent - Set default to 100% preview size and use proxies Reviewed By: sergey, fsiddi Differential Revision: https://developer.blender.org/D10362
